There are only 13 20MHz channels in 2.4GHz, which quickly become congested due to many devices that, in turn, generate interferences. Thus, it's practically impossible to connect to 40MHz channels in that frequency band.
Assalamualaikum friends@LifeWithAamir In this video discuss about 2.4ghz wireless channel width, who's best in 20mhz or 40mhz ?@LifeWithAamir For more videos
Channel Bandwidth: 20MHz, 40MHz (40MHz optional) 20MHz, 40MHz, 80MHz, 80+80MHz & 160MHz (40MHz support made mandatory) 20MHz/40MHz @ 2.4GHz, 80MHz, 80+80MHz & 160MHz @ 5GHz. Subcarrier Spacing
What users do not know is that to obtain this speed it is necessary to act on the router and configure the Band Width item (in some routers also called Band Width, WiFi Bands or WiFi 20 MHz or 40 MHz).
Networking. Frequency Bandwidth: 20MHz vs 40 MHz vs Auto. We have two wireless AP's in the house, one is from the ISP provided router and one is a WiFi repeater. Our area isn't congested, though there are times when two of my neighbors' AP's pop up randomly.
In theory, 40Mhz has twice the channel bandwidth compared to 20Mhz, and the theoretical data transmission rate is also twice as high; However, from a practical application perspective, setting a higher bandwidth has a greater chance of conflicting with surrounding WiFi signals, which can affect the actual data transmission rate.
20MHz memiliki bandwidth 20MHz, sedangkan 40MHz memiliki bandwidth 40MHz. Dengan kata lain, 40MHz memiliki dua kali lipat bandwidth dibandingkan dengan 20MHz. Perbedaan Kecepatan. Perbedaan utama antara 20MHz dan 40MHz adalah kecepatan.
